When asked where the intruders were, Peters said one was by the back door and another crawled into another bedroom.

At the time, he thought he had only shot two intruders, saying the third ran outside. Deputies later found that man's body in the driveway of the house.

The intruders were identified as 19-year-old Maxwell Cook, 17-year-old Jacob Redfern and 16-year-old Jaykob Woodriff. Authorities say one of the alleged suspects was found to have a knife, while another was carrying brass knuckles.

“Preliminary investigation looks like it’s self defense,” said Wagoner County Sheriff’s Deputy Nick Mahoney, cautioning the investigation was continuing into the midday home invasion.

A 21-year-old woman, identified as Elizabeth Rodriguez, was arrested and is likely facing three counts of first-degree murder and three counts of first-degree burglary.

Rodriguez was supposed to be the getaway driver, investigators say, but she fled the scene after hearing gunshots. If someone dies in the commission of a felony, Oklahoma law allows all suspects to be charged with murder, even if they did not actually kill anyone.

Mahoney said it did not appear the residents and intruders knew each other.
